Jackass 3Ddominated with a $50 million debut, per estimates. It was easily the stunt gang's biggest opening yet; it was Hollywood's biggest opener since Inception three long months ago; it was 3-D's biggest opener since Despicable Me three-and-a-half longer months ago.

Bruce Willis' and Helen Mirren's AARP-eligible crew from Red ($22.5 million) was a distant second, and less potent than Sylvester Stallone's own oldster actioneer from the summer, The Expendables. But Red's debut was solid nonetheless. Also, audiences liked—moviegoers graded it an A-minus—so it may stick around.

The Social Network ($11 million; $63.1 million overall) dropped to third after a two-weekend reign at No. 1.

The low-budget (no-budget?) thriller 'N-Secure, featuring former Cosby kid Tempestt Bledsoe, was a surprise contender, grossing $1.4 million, and nearly making the Top 10 despite playing on two thousand or so fewer screens than the average Top 10 movie. By comparison, the Tea Party doc, I Want Your Money, made just $279,240 on roughly the same number of screens.

Elsewhere, among the holdovers, Easy A broke $50 million overall; The Town broke $80 million; and The Kids Are All Right has crossed $20 million.
